The tangential action of mixing and kneading is thoroughly obtained by two 'Z' shaped kneading blades, which rotates very accurately at different speed towards each other causing the product to be transferred from one blade to the other.
The mixing action is a combination of bulk movement, stretching, folding, dividing, and recombining of the material. The shearing & tearing action of the material against blades and the side walls causes size reduction of the solids.

Sigma Mixer Operation

Sigma mixer, the
tangential action of mixing and kneading is thoroughly obtained by 'Z' (SIGMA) shaped
kneading blades, which rotates very accurately at different speed towards each
other causing product to be transferred from blade to blade. Discharge of the
mixed product is achieved by tilting the container or through the valves at the
bottom or by means of an extrusion screw below the container if provided
